The true falseface

I have been hiding who and what I am for 20 years.  I realized that I was not 'right' when I was about 10 years old.  I don't know what to do.  I feel so worthless.  My mother suffered from depression for many years.  I watched her go through it without any help.  I am now a mother myself and I cannot let my son grow up seeing me like this.
